The Schedule referred to in these Letters Patent and making part of the same.

To all whom 'it mol/y concern:

Beit known that I, M. W. MARS-HALL, of Hudson, inthe county .of Lenawee, and in the State of Michigan, have invented certain new and useful Improvements in Skates; and do hereby declare that the following is a full, clear, and exact description thereof, reference being had tothe accompanying drawings, and to the letters of reference marked thereon.

The nature of my invention consists in so constrnct- LetterA represents the foot-plate, which restsuponv the two standards, e, and which can be made of either wood or iron. Towards the rear end of this plate there is a long `slot cut,.in. which the'elampB moves forward and back,

while upon the same end thereisA placed a projection, sharpened on its inner side, against which the heel bears.

Upon the under side, towards the front, there are twol or more -buttons attached, upon which the endof the strap O is fastened.

Passing through the two` standards, e, is the shaft D, which has two slots cut through its frontend, one on each side of the standard, .through which the strap is passed, so that when the shaft is turned, the strap will wrap around it, so as -to tighten over the foot.

In front of the rear standard this shaft is cnt like a screw, so as to operate the heel-clamp B.

The end of this shaft is formed intoa thumb-screw, so that the shaft can be turned without v.the use of a key, and is ready for use at all times.

Just in the rear of the standard there is a ratchet cut or placed, in which the dog E catches, so as to hold the shaft, after it has once been turned, so as to fasten the skate tothe foot.

IVorking upon the shaft, and in the slot in the footplate, is the heel-clamp B.

The edge of this clamp towards the heel is cut like a saw, so that it will securely hold the heel after once catching it.

In turning the shaft, this clamp is not only operated, but the strap tightened or loosened at the same time.

.Having thus described my invention, I

What I claim, and desire to secure by Letters Patent, is-

1. The shaft D, which has one or more slots in its end, a screw-thread and ratchet' upon its surface, and one end so formed as rto be used as a thumb-screw, substantially in the manner and for -the purpose specilied.

2..'1he screw-shaft D and strap 0,' constructed and arranged as described, for the purpose of fastening the skate to the foot, substantially as herein set fort-h.

3. In combination with the screw-shaft D and strap C, the clamp B, working on the same shaft, substantially as and for the pur-poses herein set forth.

In testimony that I claim the foregoing, I have hereunto set my hand, this 10th day of April, 1869.
